Contest Winner Draw Method (EuroMillions)
This is a guide to a method used to determine winners in events/competitions based on the draw of the EuroMillions Lottery. This method was originally introduced by MindStar9 in 2006 during the first generation CND era, and again in 2009 to be used with MindStar Radio events:MSR Contest Winner Draw Method.
There is a tool for convenience: Contest Winner Draw Tool.
| How it works | Example |
| A number will be assigned to each entry in the order posted beginning with the number zero.
|
|
| Every Friday the EuroMillions Lottery generates 5 numbers + 2 lucky star numbers that are published at EuroMillions Results.
|
      
|
| An integer is formed from the drawn numbers and lucky star numbers. | 9, 14, 19, 21, 34, 5 and 7 would give 91419213457. |
Then the Modulo operation will be used to calculate the winning number as follows:
The Modulo operation results in the "Modulo" - the remainder on a division of one number by another number. This modulo represent the designated number of the winning entry. |
91419213457 Mod 25 = 7 The Designated Number of the winning entry is 7. |
| An easy way to calculate the "Modulo" is the Windows Calculator: Start -> Programs -> Accessories -> Calculator |
|
If more than one winner is to be determined (1st, 2nd, 3rd place) then the divisor in the Modulo operation is dropped by 1, and then 2, and so forth to determine all winners:
|
91419213457 Mod 25 = 7 (= 1st place)
|
This method has been used in the following events:
- MindStar Radio Contests
- The EBOA Circuit
